COVER-FASTENING FOR PACKlNG-RECEPTACLES.

SPECIFICATION forming part of Letters Patent No. 272,873, dated February27, 1883.

Application filed September 14, 1882.

To all whom it may concern Be it known that I, SPENCER L. FRASER, a

- down the removable covers of packing pails,

tubs, barrels, casks, boxes, and other similar receptacles. This classofreceptacles,as heretofore constructechhave either been devoid of acover, having merely heads, to remove which it is necessary to start thehoops, thereby causing a leakage of the liquid contents, or their covershave been fastened by devices too complicated and expensive to beeconomically applied to receptacles for packing goods to be placed uponthe market. a

A further object of my invention is to provide a cover-fastening with acheap, effective, and easily-applied lock, in order to preventpill'ering of the contents of the receptacle.

The accompanying drawings illustrate my invention as applied to thecover of a packing pail or tub.

Figure 1 is a plan of the pail, showing the cover. fastened down. Fig. 3is a similar plan; but-the cover is here shown as unfastened. Fig. 3 isa vertical mid-section cut in the plane of the line 3 3 in Fig. 1, andshowing the cover fastened down. Fig. 4 is a vertical mid-section of thepail cut in the plane of the line as in Fig. 1, and showing the coverand its fastenings in side elevation. Fig. 5 is an enlarged plan of partof the cover-fastening. Fig. 6 is a longitudinal section of Fig. 5 onthe line 6 6- therein. Fig. 7is a transverse section of Fig. 5 on theline 7 7 therein.. Fig. 8 is a plan of a modification, and Fig. 9 is avertical section thereof answering to Fig. 3.

A designates the pail as a whole, and B its removable cover. The pail ishooped in the usual manner, and has the usual bottom head, 0; and, inaddition thereto, it has an annular top or upper head, D, the centralopening in which serves for unpacking and packing the pail. The cover Bfits into this opening, and has a flange, 1), Figs. 3 and 4, which, whenit is in place, rests on the head D. Beneath this (No model.)

flange is placed a rubber or other elastic packing-ring, a, which, whencompressed in the tightjoint between the cover and head.

On opposite sides of the pail, close to its staves, and on top of itsupper head, are fixed two cleats, E E, or other'provisions, havingoverhanging shoulders. These shoulders are shown as formed by mortisingout the under side of each cleat, as indicated in dotted lines in Figs.1 and 2, and as shown in section in Fig. 3. I shall refer to theseoverhanging shoulders by the letters 6 0, it being understood that itisimmaterial how they are formed,

cient strength to withstand the upward pressure necessary to securelyfasten down the cover. On the top of the cover B are two bolts, F F,arranged in line with each other and extending diametrically of thecover. These bolts are arranged to slide longitudinally for a shortdistance, being connected to the cover in any suitable way. I have shownthem as having slotsff, through which pass screws 0 c,driven into thecover B, which is a cheap and simple connection. Between the adjacentends of the bolts F F a wedge, G, is arranged in a direction at rightangles to the axis of the bolts.

On each side of the wedge, and projecting therefrom in a horizontalplane, is a plate or wing, H, which, it the wedge is made of metal, maybe cast inone piece with it; or they maybe overhanging parts of aseparate plate or thin board fastened to the top of the wedge. Thesewings H H are formed with two slots, h h, ex tending parallel to the twoinclined sides of the wedge, and each slot engaging a screw or otherprojection, d, on the bolt F. When the wedge- G is driven in, itsinclined sides thrust apart the bolts F F, as shown in Fig. 1. When theWedge isdriven back by striking its narrow end, the sides of the slots hh act on the projections 61 (Z and cause the bolts F F to move towardeach other, as shown in Fig.2. Hence to apply the cover after havingpacked the pail, the wedge being driven back and the bolts retracted,the cover is put. in place, as shown in Fig. 2, with the bolt endsopposite the snoulders e e, and the wedge Gris driven home tightneaththe shoulders e 0. Either the shoulders act of fastening down the cover,forms a waterso that they are fixed to the pail and have suffi- 1y,thereby projecting the ends of the bolts be- 'or the tops of the boltends are beveled or inclined, or both are so formed, as shown in Fig. 3,in order that as the bolts are driven out they will act as wedges toforce the. cover down firmly on its seat and make a tightjoint.

To open the pail the wedge is driven back, which retracts the bolts andpermits the cover to be lifted off. Thus a few blows ot' a malletsnffice either to close or open the pail.

The wedge Gr may be kept in place on the cover by means 6f screws 61 (1,whose heads overhang the slots h h, and thereby prev'ent theliftingorverticaldisplacementofthewedge; but this is not necessary in theconstruction shown, which is mostclearly illustrated in Figs. 5, 6, and7. The wedge G has a longitudinal slot,g, formed in it,extending nearlyto its ends. In this slot is placed a cleat or bridge, I, which isscrewed down to the cover 13. This bridge is formed of a top piece, t',and two legs,j j. The former stands above the top surface of the wedge,and thelatter rest on the cover B and have shoulders]; 70, whichoverhang the top of the wedge and serve to keep the wedge from lifting.

On one side of the top pie e, t, is a downwardly-projecting flange, m,formed with halfronnd notches, and on the wedge, just beneath thisflange, is another upwardly-projecting flange, n, having also half-roundnotches ot' the same size, but differently spaced, after the manner of aVernier. As the wedge is driven the flange m moves over the flange a,and one after another of the upper and lower notches coincide to formcomplete holes. When the wedge is driven tight a pin or key, 0, isdriven into the hole formed by the two coinciding notches, therebypreventing the wedge from becoming loose or from being driven back untilthe pin has been removed. To prevent pilfering, a padlock or seal mightbe passed through this hole.

It will be obvious that this device might be modified in many wayswithout essentially changing it. By its means a very simple and cheaplock is formed.

To keep the wedge from becoming loose, a series of holes might be madetranversely through its small end and a pin driven into either of theseholes, with its end projecting.

My invention is applicable to kegs, casks, and barrels, as well as topails, it being only necessary to form a large opening in the upper headand provide the cover and fastening which I have described. It may alsobe applied to tubs and boxes. In Figs. 8 and 9 I have shown it asapplied to a tub, such as a butter-tub. Thereisnotophead,D,theflangedcover resting directly on the top of the tub instead. The shonlders e eare form d as holes in two outside staves or projecting strips, E E,which are fastened to the outside of the tub and project above its top.Otherwise this construction is the same as that shown in Figs. 1 to 4.

I am aware of the fastening for boxes shown in the patent of Simpson,No. 222,745, dated December 16, 1879; but this differs from mine in thatthe fastening bolts and wedge are arranged beneath the cover instead ofon top--a construction which necessitates making holes in the receptaclethrough which to manipulate the wedge, and which is consequentlyunsuited to the packing of liquids or wet goods, because of thepractical impossibility of preventing leakage through said holes. in myreceptacle the only opening into the interioris that which is closed bythe cover when it is in its place.

I claim as my invention 1. The combination, with pail or otherreceptacle A and overhanging shoulders e e, fixed thereto above the seatfor the cover, of cover B, fitting tightly over said seat, sliding boltsF F, arranged on the top of said cover, and wedge Gr. arranged betweenthe adjacent ends of said bolts, substantially as set forth.

2. The combination, with pail or other receptacle A and shoulders e e,of cover 13, bolts F F, projections 01 d thereon, wedge G, plates H,fixed thereto, and slots h h in said plates, substantially as set forth.

3. The combination, with cover B, of bolts F F, wedge G, having slot gtherein, and cleat or bridge I, having shoulders 7c 7r, substantially asset forth.

4. The combination, with cover B, of bolts F F, wedge G, a series ofholes or notches on said wedge, and a series of holes or notches on afixed part spaced differently, so as to vernier with those on the wedge,whereby when the wedge. is driven a key may be inserted through thecoinciding hole or notches, to lock the wedge in place, substantially asset forth.

5. The combination, with cover B, of bolts F F, wedge Gr, slot gtherein, cleat or bridge I, notched flange m on said bridge, and notchedflange a on said wedge, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
